"Time Heist" is a stunningly mediocre 45 minutes of television, another example of Steven Moffat's love for high-concept time-travel complexity and Big Ideas that are never fleshed out but only declaimed (mostly by the Doctor) at a machine-gun pace.

By the time the episode was over, and all the unlikely explanations for the episode's events were in, I could for a change accept the bare logic, but still couldn't accept the motivations.

Possibly because I just didn't care enough. And I don't care enough to think about it (or to write about it) any further. If you're interested in a detailed critique (that surprised me by being less harsh than I expected), I commend your attention to "Mooning: Time Heist", by the blogger Patches365.

As for me, I live-tweeted my initial reactions very early on the morning of September 21, 2014. (Follow me here, if you want to) For the record (why doesn't Twitter include the times as well as the dates of posts? Oh well ...), I've pasted them below, oldest to newest, hash-tags removed for easier reading and with replies interspersed (all two of 'em). Also, edited for typos, but that's all.
